民航移动通信中TCP协议的改进

Improvement and research of TCP protocol in civil aviation mobile communication

摘要:

针对民航移动通信中民航客机内移动终端与地面用户端到端通信的大时延、高随机误码和突发误码的特点，在TCP Veno的基础上提出了增大初始发送速率，拥塞快速恢复，突发误码快速恢复等优化策略。用OPNET将本文算法与Veno进行了仿真比较，仿真结果表明，本文算法较好地克服了大时延和突发误码丢包问题，显著提高了TCP吞吐量。

Abstract:

In order to realize reliable end-to-end communication in aeronautical mobile communica- tion between mobile terminal in aircraft and ground user host, this paper proposes some strategies such as higher initial sending rate, fast recovery for congestion, fast recovery for burst error. Comparing this algorithm with TCP Veno by using OPNET, the simulation results show that the proposed algorithm can solve the problem of high latency and burst error loss, and significantly increases the TCP throughput.
